Utility model content
The technical problems to be solved in the utility model is the fuel tank fixed sturcture providing a kind of indefatigability to rupture.
For solving the problems of the technologies described above, the fuel tank fixed sturcture that the utility model provides comprises drawstring, positioning head and binding bolt, described positioning head and described binding bolt are connected with the two ends of described drawstring respectively, wherein, described positioning head comprises location division connected in turn, connecting portion and fixed part, one end of described location division and cross member of frame offset away from the surface of fuel tank, the outline of the other end of described location division is arc, and one end that described connecting portion offsets with described location division and cross member of frame is connected.
Preferably, described location division and described connecting portion junction are provided with the groove extended towards the direction away from described connecting portion.
Preferably, described fixed part is the structure of nearly equicrural triangle.
More preferably, the one end on the base of described fixed part is connected with described connecting portion.
Preferably, also comprise flexible liner, described flexible liner is provided with drawstring groove, described drawstring is arranged in described drawstring groove.
Preferably, described cross member of frame is provided with knock hole, described knock hole is made up of the macropore be connected and aperture.
The stress dispersion produced because of car load vibration can weaken on ground by the location division of the positioning head of the fuel tank fixed sturcture that the utility model provides, thus effectively prevents connecting portion stress from concentrating and fracture by fatigue.

Detailed description of the invention
For enabling above-mentioned purpose, the feature and advantage of utility model more become apparent, below in conjunction with accompanying drawing, detailed description of the invention of the present utility model is described in detail.
Set forth a lot of detail in the following description so that fully understand the utility model, but the utility model can also adopt other to be different from alternate manner described here to implement, those skilled in the art can when doing similar popularization without prejudice to when the utility model intension, and therefore the utility model is by the restriction of following public specific embodiment.
As shown in Figures 2 to 4, the fuel tank fixed sturcture that the utility model provides, comprise drawstring 1, positioning head 2 and binding bolt 3, described positioning head 2 and described binding bolt 3 are connected with the two ends of described drawstring 1 respectively, above-mentioned being connected realizes by welding or the mode such as bolt connection, and above-mentioned positioning head 2 and binding bolt 3 are all connected with cross member of frame;
Wherein, described positioning head 2 comprises location division 21 connected in turn, connecting portion 22 and fixed part 23, one end of described location division 21 and cross member of frame offset away from the surface of fuel tank, the outline of the other end of described location division 21 is arc, described connecting portion 22 is connected with one end that cross member of frame offsets with described location division 21, and on location division 21, the stress dispersion be beneficial to the vibration because of cross member of frame produces that is designed with of arch section weakens.
The stress dispersion produced because of car load vibration can weaken on ground by the location division 21 of the positioning head 2 of the fuel tank fixed sturcture that the utility model provides, thus effectively prevents connecting portion 22 stress from concentrating and fracture by fatigue.
In order to be weakened by the vibration dispersion passed over from car load better, described location division 21 is provided with described connecting portion 22 junction the groove 24 extended towards the direction away from described connecting portion 22.
In order to be weakened by the vibration dispersion passed over from car load better, described fixed part 23 is the structure of nearly equicrural triangle.
Further, the one end on the base of described fixed part 23 is connected with described connecting portion 22.
In order to better the vibration dispersion passed over from car load be weakened, and prevent drawstring 1 to wear and tear the outside face of fuel tank, also comprise flexible liner 4, described flexible liner 4 is provided with drawstring groove 41, described drawstring 1 is arranged in described drawstring groove 41, when installing fuel tank, flexible liner 4 and fuel tank are affixed.
In order to more easily positioning head is positioned on cross member of frame, described cross member of frame is provided with knock hole (not shown), described knock hole is made up of the macropore be connected and aperture, like this, the macropore in the self-align hole, location division 21 of positioning head 2 enters, and fixes in the aperture of knock hole.
Although the utility model is described in conjunction with above embodiment, but the utility model is not defined to above-described embodiment, and only by the restriction of claims, those of ordinary skill in the art can easily modify to it and change, but do not leave essential idea of the present utility model and scope.
